A New Zealand judge sentenced white supremacist Brenton Tarrant to life in prison without parole on Thursday for killing 51 Muslim worshippers in the country’s deadliest shooting, saying the sentence was not enough punishment for the “wicked” crimes.

It was the first time a court in New Zealand had sentenced a person to prison for the rest of their life.

Tarrant, a 29-year-old Australian, admitted to 51 charges of murder, 40 counts of attempted murder and one charge of committing a terrorist act during the 2019 shooting rampage at two Christchurch mosques which he live-streamed on Facebook.
